Embodiment Construction

[0040] The present invention will be described below through detailed description of the embodiments.

[0041] exist Figure 1A, a schematic diagram of a pinhole array-based tactile sensor is shown. The device comprises a reflective layer 1 for illumination reflection, an elastomeric layer 4 on top of which is a marker 2, one or a series of LEDs 3 to provide illumination for imaging, a pinhole-based lens structure 5 and a CMOS (complementary metal oxide Semiconductor) sensor 6. One or a series of LEDs 3 will provide illumination to the elastomeric body 4 and they are located on the side(s) of the elastomeric body 4 .

[0042] In this embodiment, the reflective layer 1 is a flexible layer with high light reflectivity, and its shape can be changed according to external touch. The material of the reflective layer 1 can be silicone resin, parylene C, polyimide and other polymers, and other inorganic materials, as long as it can be deformed by combining with the underlying elasti...

Abstract

The present disclosure provides a sensing device, a tactile sensing device, and a tactile sensor. The sensing device includes: a photosensitive sensor; a pinhole array structure located on the photosensitive sensor; an elastomer layer positioned on one side, far away from the photosensitive sensor, of the pinhole array structure; a reflecting layer positioned on one side, far away from the pinholearray structure, of the elastomer layer; and a light source located between the reflective layer and the pinhole array structure.

Description

technical field [0001] The present disclosure relates to vision-based tactile sensors, especially for sensing three-dimensional surface deformation and force distribution in contact areas. Background technique [0002] Tactile sensors are currently used in many fields, such as robotics and medical surgery. For example, for a grip-operated system, tactile sensors are necessary to generate effective feedback to maintain a stable grip during movement. [0003] Various types of tactile sensors with different conversion methods, including capacitive, piezoelectric, and piezoresistive, have been widely developed in recent decades. They cover a wide range from micro to macro and have a wide range of applications. However, they lack the capability of high-resolution spatial mapping and three-dimensional measurement due to their high complexity in terms of mechanical structure, readout circuit design, and interface. [0004] Vision-based tactile sensors are flourishing in various ...
